c# - 可访问性不一致:与使用WCF MEX的方法相比，参数类型的访问性较差

我正在分配作业，但出现此错误：


  错误1不一致的可访问性：参数类型'MexWcfService.MyComplex'的访问权限比方法'MexWcfService.Calculator.complex_sum（MexWcfService.MyComplex，MexWcfService.MyComplex）'E：\ North Central College \ CSC615 \ lab8 \ MexWcfService \ MexWcfService \ Program。 cs 75 26 MexWcfService


下面是我的代码。我的问题发生在..public MyComplex complex_sum（MyComplex a，MyComplex b）的接口实现类内部...

有人可以帮我吗？我对C＃相当陌生，更不用说WCF和元数据交换端点了。任何指针将不胜感激。

最佳答案

您需要将“ MyComplex”类声明为公共类，因为您已经在Calculator类中的公共方法中使用了该类型。
